Non-absorbent materials do not take in or soak up liquids. This means that when a liquid is placed on a non-absorbent surface, it will remain on top rather than being absorbed. Common examples of non-absorbent materials include plastic, glass, and metal. These materials are often used in situations where it is important to keep surfaces dry or to prevent contamination. In everyday life, non-absorbent items can be found in various products, such as waterproof clothing and kitchen utensils. These items are designed to resist moisture, making them easy to clean and maintain. Non-absorbent surfaces are also useful in laboratories and medical settings, where hygiene and cleanliness are crucial.
